While partaking in the mad race of economic growth and in our pursuit of wealth and prosperity, we humans have alienated ourselves from Mother Nature. As a result, we have started facing disastrous consequences. We have played dangerously too long with nature. Nature is now hitting back at us. Destruction and over-exploitation of mother Earth has led to climate change, which in turn poses fundamental threat to almost all the ecosystems. An ecosystem is any geographic area like forests, lakes, deserts and mountains, where plants, animals, and other living organisms exist together. If one component is adversely affected then the whole equilibrium of that ecosystem gets disturbed. This is what has happened today with mother nature and its constituent ecosystems.
